Enum Access

Access

An enum representing classes of users who can access a file or folder, besides any individual
users who have been explicitly given access. These properties can be accessed from DriveApp.Access.

// Creates a folder that anyone on the Internet can read from and write to. (Domain
// administrators can prohibit this setting for users of a G Suite domain.)
var folder = DriveApp.createFolder('Shared Folder');
folder.setSharing(DriveApp.Access.ANYONE, DriveApp.Permission.EDIT);
